Absolutely nailed it. People love to overreact and created drama, but I'm sure it's just a matter of feeling.
I feel the need to name one other person. Roddick. His humour was a little bit dry, kinda like Murray's, and you can still tell he and Roger really get along. As a matter of fact, Roddick was the only person to actually call him a selfish bastard on an interview and get away with it.
Djokovic, on the other hand is either forcing himself down people's throats like "you NEED to love me" or just ripping shirts and pulling faces that would make anyone uncomfortable.
Federer gets along with Roddick the most out of all of them. Roddick has the right balance of dry humour and wits, doesn't shy away from the spotlight, while Murray can sometimes be seen uncomfortable or even annoyed with the media. Rafa is never truly himself when he has to talk in English. Roger is actually an incredibly relaxed guy, same as Roddick, I guess that's why they get along so well I guess.
